Given numbers are 388,138,209,298,666

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 388,138,209,298,666 is 92541460572.

Find LCM of 388,138,209,298,666 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 3 x 194 x 23 x 209 x 149 x 111 = 92541460572

Therefore, the lowest common multiple of 388,138,209,298,666 is 92541460572.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

388 x 138 x 209 x 298 x 666 = 2220995053728

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

388 : 1, 2, 4, 97, 194, 388

138 : 1, 2, 3, 6, 23, 46, 69, 138

209 : 1, 11, 19, 209

298 : 1, 2, 149, 298

666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,138,209,298,666, is 1.

Now, the common factors can be found like this.

388:2x 2x 97

138:2x 3x 23

209:11x 19

298:2x 149

666:2x 3x 3x 37

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 2x 3 = 24

Therefore, the value for common factors is 24.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 2220995053728/(1x24)

LCM = 2220995053728/24

LCM = 92541460572

Thus, we can understand that the LCM of 388,138,209,298,666 is 92541460572.
